Bluetooth-Controlled Boat
Personal Goal: To grow my understanding of electromechanical systems to make the most of my quarantine
Project Goal: To build a boat that can be driven wirelessly on water using recycled parts
Plan: Separate the electromechanical components into the controller unit and the receiver unit. Connect both units via Bluetooth (UART communication) so that once the receiver unit sits inside the boat made of recycled parts it can be controlled from a distance of ~10m.
Implementation
Controller Unit:
Its purpose is to send the required information to the boat to act accordingly. The Bluetooth module sends the position of the joystick to the onboard Bluetooth module.
Receiver Unit:
Its purpose is to do what the controller unit tells it to do. The Arduino Nano interprets the instructions received through the Bluetooth module by controlling the motors accordingly.
End Product
The electronics are safely secured inside a container with wires connected to the motors. At the back, there is a rock and an eraser hot-glued to the boat to act as a counterweight.
The water level is below the motor shaft due to the counterweight, preventing the water from entering.
